Partial discharge wireless intelligent monitoring system

Abstract

The invention relates to the technical field of electronic information systems, and discloses a partial discharge wireless intelligent monitoring system. The partial discharge wireless intelligent monitoring system comprises partial discharge collectors, RFID readers, a data server and a processor unit, wherein the partial discharge collectors are connected with surfaces of a measured object; the partial discharge collectors are connected with the RFID readers by means of radio frequency signals; the RFID readers are connected with a data server; the data server unit is connected with the processor unit; and the processor unit carries out longitudinal comparison on voltage information of the surfaces of the measured object, judges time when a failure occurs, and alarms when the failure occurs. The partial discharge wireless intelligent monitoring system adopts the RFID readers to read the radio frequency signals of the partial discharge collectors, is high in anti-interference capability and high in data sensitivity, can realize the measurement of a plurality of the measured objects, especially the measurement of a plurality of detection points in the same system, and can find out a failure source through horizontal comparison.

Description

technical field [0001] The invention belongs to the technical field of electronic information systems, and relates to a wireless intelligent monitoring system for partial discharge. Background technique [0002] The insulating layer inside the high-voltage switchgear will crack and partially discharge under the long-term effects of electricity, heat, and the environment. Most of the failures of high voltage switchgear are caused by insulation failure. The short-term existence of partial discharge may not affect the insulation strength of electrical equipment, but if partial discharges continue to occur on the insulating layer of high-voltage switchgear under the operating voltage, these weak discharges will have a cumulative effect, which will gradually deteriorate the dielectric properties of the insulation and cause damage to the electrical equipment. The expansion of local defects will eventually lead to the breakdown of the entire insulation, which will lead to safety a...

Problems solved by technology

However, due to the large amount of interference in the field, the sensitivity of ultrasonic measurement, light measurement and other methods is much lower than the sensitivity of measurement under shielded laboratory conditions. Not many have been successfully used in monitoring systems, and the effect is not ideal.
